UV/OV LED

  •          Solid Red: Output is isolated from the grid due to either an Over Voltage or Brownout (under voltage).
  •         Flashing Red: Flashes for 1 hour after recovery from either an Over Voltage, Brownout(Under voltage), or voltage sag.

 

CVSS or Current Surge LED

  •        Flashing Red: Flashes for 1 hour after recovery from Voltage Sag

 

TVSS or Voltage Surge LED

  •       Flashing Red: Flashes for 1 hour after recovery from a Voltage Surge
